The school record in the 200-meter dash is 34.5 seconds. Which graph represents the set of times, in seconds, that would create a new school record?

Vocaloid:

well, if 34.5 is the old record, then any score above 34.5 will beat the record right? which graph shows all the scores that are above 34.5?

GAT0R:

C and D

Vocaloid:

getting closer "above 34.5" means 34.5 is not included, so the graph would have an open circle on 34.5

GAT0R:

A & B are below and D has a closed circle so it has to be c

Vocaloid:

excellent

GAT0R:

thanks
